High speed data streams are everywhere in the fifth generation (5G) system measurement. To develop a high efficient and low cost 5G testbed in a reverberation chamber, the authors propose a high efficient measurement method in the time, frequency and space coherence measurement. In this study, the one‐bit technique is introduced to measure the time domain, frequency domain and space domain correlations in a reverberation chamber. The coherence time, coherence bandwidth and correlated angle can all be measured using the one‐bit correlation; float number calculations are simplified to logical operations which accelerate the data processing greatly. Measurements are performed to verify the results.
